Molecular interactions of triethylamine and 1-dodecanol binary liquid mixtures

Abstract

Solute -Solvent interactions of Triethylamine (TEA) and 1-Dodecanol binary mixture have been carried out for 11 concentrations at different temperatures using LCR(Inductance (L), Capacitance (C) and Resistance (R)) meter at a frequency of 1 KHz. The Kirkwood correlation factors and excess dielectric properties were determined and discussed to give information about the molecular interactions of the systems. The static dielectric constants for the mixture have been fitted with the modified Bruggeman model. The excess permittivities are found to be positive for all concentrations and temperatures, which represent solute and solvent interact in such a way the effective dipole moment increases.

“… temperatures [57] should be taken with caution, as they are rather scattered and the corresponding curves are S-shaped, with positive values at higher concentrations of the alkan-1ol which increase in line with the temperature [57]. This needs further experimental confirmation.…”
